Be it known' that I, EowAnnHsss, a citithese looped rein-forcing devices is disclosed, ca o, in the' county` of Cook and State of i in Fig. 1, .its detailed construction being Illinois, have invented it new andusefull ilhistratedin Fig. 3,' but the saine device Imrovemcnt in Spring Vehicle-Tires, of 1 K which the following is a specification. y or four places, equidistant apart, about the My invention relates to an improvement spring. j 'I in the class of spring-'tires for vehicles in For tightening the; spring about the rim which thetire comprises an endless spiiiiga. hand in' the preferred form of a chain 19 coil conined about the wheel-rim and enl-is employed.

The. brace shownf is of general yolie-shapc with transverse froovcsA 15 near its eiidsto lreceive the coils, to which the brace. is rigidly fastened by theI heads of screws 16 inserted into-the inner side. of the yoke; and a loop t7 straddles the yoke inidl hed with a step-like action an'd tend to disthe tread in contact with the road-bed, with way between its' ends and is fastened thereto through its wings hy ay pin 18.

What I claim as new and desire to secure by Letters Patent is 1. In u spring tire, the combination of a continuons spiral spring seating about An wheel-rim inside u casing; independent curved metal shoes in Series about the spring pivotnlly supported on vthe coils thereof to y wheel-rim inside n czlsinfa band about tho rim within the spring for securing the latter in-place, braces at intervals about 4the Seating portion of the spring connecting succesSive coils thereof, loops extending from the braces into the path through the spring of said bund :md through which it passes for its confinement, and means at tne opposing ends of the bnd for tightening il', for the purpose set forth.'

3. In va spring tire, the combination of a Ipirul spring seating about a wheel-rim inside a casing, n band about the lrim within the spring for securing the latter in place, a; metal plate seating inside the-s ring'nt the band-ends and provided with eanngs, links on the ends of the band terminating in screws, nuts journaled in said bearings and working` on said screws; beveled gearson the djzcent ends` 'ofthe nuts, arid a keyoperated. v stem journaled in said plate to extend through the'rimand provided on its inner end 'with n beveled gear meshing with the gears .on said nuts,' for the purpose set forth.
